Specification of Letters Patent.

Patented Jan. M1 1922.

Application filed. September 23, 1920. Serial No. 412,212.

To all whom it may concern:

Be it known that we, EDWARD GRAHAM and l/VILLIAM A. GRAHAM, citizens of the United States, residing, respectively, at St. Paul, in the county of Ramsey and State of Minnesota, and Chicago, in the county of Cook and State of Illinois, have invented a new and useful Cooking Attachment for Gas and Oil Stoves, of which the following is a specification.

Our invention relates to cooking attachments for gas and oil stoves, and the object is to provide a stove attachment which will distribute heat from a single burner to several cooking vessels without allowing the distributed hot air to escape and get in contact with the hands or the clothes of the operator. Another object is to provide such attachment with a special heat spreading device which is detachably suspended over the fire of the burner.

In the accompanying drawing:

Fig. 1 is a plan or top view of our cooking attachment in position for use upon a gas stove from which some of the kettle supporting grates are omitted. Fig. 2 is a section on the line 2-2 in Fig. 1 of the attachment, a portion of the upper part of the gas stove is also shown intact but with the gas supply pipes and valves omitted. Fig. 3 is a top view of the rear portion of the attachment showing a modification. Fig. 4 is a modifipation of the upper right hand corner of Referring to the drawing by reference numerals, 5 designates any form of gas or oil stove used for cooking purposes. It may have only one burner but we have shown the type having four burners 6, 6 6, 6, supplied with gas from a pipe 10 having branches 11 with valves 12.

The attachment comprises a triangular fiat metal box 13, having in its bottom a central aperture 14 adapted to go over the fire 15 of the burner 6, or any burner accessible. The top of the box is provided with a cook ing hole 16 near each corner and one central cooking hole 17. Each of said holes has its edge recessed as at 18 for a lid 19 when the hole is idle.

Suspended in the recess 18 of the central hole 17 are hooks 20, which are formed at the upper ends of arms 21, which have their lower ends secured to a metal disc or heat spreading plate 22, which is thus held above the fire 15, of the burner 6. 24 designates a cooking vessel placed over the fire 15 and the plate 22. 7

Near up under the edges of the top 25 of the attachment extends all around the same a pipe 26 having air holes 27 and terminates in a vertical outlet tube 28 which may project a foot or so above the top of the attachment.

In the modification Fig. 3 the outlet tube 28 extends upwardly through the top of the box 13 while in Fig. 1 it is shown as placed back of the box and connected through the rear side of it with the perforated tube 26.

In Fig. 4 the tube 26 is shown as cast in tegral with the box; but in either case only the curves of the tube are perforated, so that when the apparatus is in use the hot air, indicated by arrows 29 in Fig. 2, will move along underneath the kettle opening 16 in order to reach the perforations 27. The spreader plate 22 being suspended below the kettle 24 some of the heat will reach the kettle and then be deflected as the arrows 29 while the plate 22 will spread much of the heated air directly to the kettle (not shown) placed in the holes 16, and then escape through apertures 2'7, the pipe 26 and vertical pipe 28, or 28. The hot air is guarded and guided out of the device without having a chance, as in earlier cooking attachments of similar construction, to escape through many vent holes in the side or top ofthe burner and burn the hands or clothes of the operator.

What we claim is:

The combination with a gas or oil burning stove, of a triangular fiat metal box having a central bottom opening adapted to be placed over a burner of the stove, and a central cooking aperture in its top and a cooking aperture near each corner of the top, a pipe extending in triangular form all along the edge of the top within the box and terminating in a sin gle upright stack near the rear of the box, said pipe within the box having a series of perforations in each of its angular curves, and a heat spreading plate supported in horizontal position over the burner by vertical arms having hooks engaging over the edges of the central aperture in the top of the box.

In testimony whereof we affix our signatures.

EDWARD GRAHAM. WILLIAM A. GRAHAM.
